Abstract
Provided are a glass composition, a dielectric composition and a multi-layer ceramic capacitor embedded low temperature co-fired ceramic substrate using the same. The multi-layer ceramic capacitor embedded low temperature co-fired ceramic substrate is sinterable at a low temperature while showing a high dielectric constant. The glass composition includes a composition component expressed by a composition formula of aBi2O3-bB2O3-cSiO2-dBaO-eTiO2, where a+b+c+d+e=100, and a, b, c, d, and e are 40≦a≦89, 10≦b≦50, 1≦c≦20, 0≦d≦10, and 0≦e≦10, respectively.
